| The Java language allows the `[]` to be placed after the declaration of a |
| variable or method: |
| |
| ```java |
| int foos[]; |
| int getFoos() [] { |
| return xs; |
| } |
| ``` |
| |
| The example above is equivalent to the following, strongly preferred, form: |
| |
| ```java |
| int[] foos; |
| int[] getFoos() { |
| return xs; |
| } |
| ``` |

| notes: |
| |
| > The declaration of a method that returns an array is allowed to place some or |
| > all of the bracket pairs that denote the array type after the formal parameter |
| > list. This syntax is supported for compatibility with early versions of the |
| > Java programming language. It is very strongly recommended that this syntax is |
| > not used in new code. |
| |
| Placing the square brackets immediately after the type is required by the |
| [Google Java Style Guide][style]. |
